NEW DELHI: Delhi Jal Board (DJB) issued an advisory on Sunday that water may be available at low pressure in large parts of the city for a few days due to inadequate supply of raw water.
The flow from Upper Ganga Canal is less due to its annual maintenance and the Yamuna has low water levels, said an official. For water tankers, people can contact the emergency number of a local area or reach out to the central control room at 1916 or 23538495.
The main areas to be affected are parts of south, east and northeast Delhi, and some areas under New Delhi Municipal Council.
The flow in both conduits of the Sonia Vihar and Bhagirathi water treatment plants (WTPs) are reducing like last year, a DJB statement pointed out. As the water production at both plants may get affected, clean water will be available at low pressure for a few days till the situation of Yamuna raw water improves, it added.
In case of low production at any WTP, water is diverted from other such facilities to minimise the overall impact on the supply, a senior officer said. But “this leads to reduction in water pressure”, he clarified.
DJB manages about 14,500km water lines to provide supply and sewerage services to about two crore people in Delhi. It has a capacity of producing 935MGD water through its nine water treatment plants, ranney wells and tubewells.
The Bhagirathi plant produces 108MGD potable water while the Sonia Vihar production can go up to 140MGD potable water under normal circumstances. Both plants are fed by raw water from Upper Ganga Canal, the Yamuna, DSB Canal and CLC Munak Canal, besides sub-surface sources.
